TIE-PLATE.

SPECIFICATION fprmingpart of Letters Patent No. 707,362, dated. August19, i902.

Application filed November 14, 1901. Serial No. 82,312. (No model.)

To all whom t Weary concern.-

Be it known that I, CHARLES S. SHALLEN- BERGER, of the city ofMilwaukee, Milwaukee county, State of Wisconsin, have invented certainnew and useful Improvements in Tie- Plates, of which the following is afull, clear, and exact description, reference being had'to theaccompanying drawings, forming a part hereof. y

This invention relates to tie-plates; and it consists of the novelconstructiomcombination, and arrangement of parts hereinafter shown,described, and claimed.

The objectof this invention is to provide an improved metallic tie-plateto support the rails to prevent the samel from cutting into the ties andwhich is formed with a series 0f ribs or projections on its under sideadapted to engage in the ties and arranged in staggered form, so thatthey will engage in different parts of the grain of the tie, so that thelatter will not be split or cracked because of their presence therein.

Figure l is a view of the tie-plate, showing the ribs on the under sidethereof. Fig. 2 is a cross-section taken on the line c. o of Fig. l.Fig. 3 is a side elevation of the tie-plate inverted. Fig. 1l is a planview of the tieplate.

In forming myimproved tie-plate I provide the plate l, which may be ofany suitable size and shape andwhich is provided with openings 2,through which the spikes can be driven to secure they rails in position.The upper side of the tie-plate is provided with an integral transverseridge or elevation 3, against which the base of the rail abuts and whichserves as a stop or brace for the same and also as a guide to assist inplacing the tie-plate in the required position. The said part 3 isbroken away adjacent to the opening 2, as indicatedby 4, so that therewill not be any obstruction in the way of insertion of the spikes. Y

5 indicates a series of longitudinal ribs or projections which areintegral with the under side of the plate and which extend somewhat morethan one-half of the length thereof. The ribs or projections extend fromboth ends of the plate and are parallel and are adapted to engage in`the tieatdifferent points and parallel with vthe grain thereof. Thetie-plate is provided with a short rib or projection 6 at one end of theprojections and out of alinement therewith to engage in al dierent partof the grain, andthereby serve to lresist thegrain frombeing forced openby the projections and topreventthe tie from becoming split or crackedthereby. It will thus be seen that the ribs or projections 5 and 6 serveas mutual stays to protect the tie and prevent the samefrom being splitby the oscillation of the tie-plate when in position. By such anarrangement the tie will be protected andthe tie-plate'willbe held moresecurely in position, forming a better protection for the tie andleaving no cracks therein within which water or mois: ture maybecomelodged to cause the tie to become weakened. The projections. 5,extending longitudinally on the tie-plate, reinforce the same and giveadditional strength to prevent it from becoming bent by long use. Thestaggered arrangement of the projections 5 6 affords double abutments tohold the tieplate against longitudinal movement, as can be seen byreferring to Fig. 2thatis, double the amount of wood must be displacedfor the tie-plate to move longitudinally than would be displaced ifthese projections were alined. Thus it will be seen that Ytheseprojections form mutual stays to hold the grain of the wood againstsplitting and cracking and also double the abutting or resistingsurfaces as well as to strengthen the tie-plate to hold the same againstbeing bent. The projection or elevation 3 also forms an abutment for therail and is` of great assistance in holding the rail in position atcurves and bends in the track. All these advantages are combined in asimple, durable, and inexpensive `tie-plateconstructed as abovedescribed.

I claiml. The improved metallicv tieplate comprising the plate l havingspike-openings 2, a stop 3 located on the upper side of said plate, aseries of longitudinal projections 5 formed integral with the under sideof said plate and extending more than half the length thereof, and aseries of shorter projections 6 arranged at one end of the saidprojections 5 but out of alinement therewith, substantially as hereinspecified.

2. Atie-plate, comprising an integral metal plate having on its undersurface two series of thin, parallel ribs, one series extending fromnear one edge to beyond the middle transverse line of the p late, andthe other series extending from near the opposite edge of the plate tobeyond the middle transverse line of the plate, the two seriesoverlapping each other at their inner ends at the middle portion of theplate.

3. Atie-plate consistin g of an integral metal plate having on its undersurface two series of ribs,oneseries extendingfrom nearone edge tobeyond the middle transverse line of the plate, the two seriesoverlapping each other at their inner ends at the middle portion of theplate, and similar elongated but shorter ribs supplemental to said longribs in the spaces at the ends of the long ribs but separated a distancetherefrom. 4

4. A tie-plate comprising an integral metal plate having on its undersurface two series of parallel ribs, one series extending from near oneedge to beyond the middle transverse line of the plate, and the otherseries extending from near the opposite edge of the plate to loe-` yondthe middle transverse line of the plate,

the two series overlapping each other at their inner ends at the middleportion of the plate, and similar elongated but shorter ribssupplemental to said long ribs in the spaces at the ends of the longribs but separated a distance therefrom, the ribs being severally out ofend wise alinement with every other rib on the plate.

In testimony whereof I alix my signature in presence of two Witnesses.
